This kit is for refreshing / refurbishing the Brompton rear hinge spindle - on the P/T Line - for use with the 9.55mm reamer
The spindle and bushings on the rear hinge are wear items. If your rear frame moves frome side to side by more than 4mm, as suggested by Brompton, it is time to examine the rear frame hinge. The original hinge spindles on P/T line are made from aluminum alloy. The hinge spindle in this kit is made from stainless steel, which will be longer lasting, although slihgtly heavier (by ~ 15g)
This kit includes the following parts:
- Stainless steel hinge spindle
- Steel/nylon bushings (x2)
- Teflon washer (x2), (Available in 1.7mm and 1.85mm thicknesses)
Please note that the hinge bolt is not included in the kit. The oginal zinc plated hinge bolt does not usually wear, and can be re-used. However, when re-installing the hinge bolt, application of medium strength thread adhesive is recommended.
Notes:
Most bikes use standard 1.7mm thick washer. For those bikes that have black washers as fitted from factory, please choose the 1.85mm version.
We believe the best way to install the bushings is to press them in, using use a proper length M8 bolt together with nuts and washers. If you don't have access to one. They are available
here.
